Astronomical Timer switch - HY

Astronomical Timer switch , DIN rail-mounted, occupies a space of 2 modules. The timer switch has a 6-year lithium battery backup to ensure the settings are not lost in the event of a power failure.

Possibility of correcting hours based on latitude, avoiding the need to regularly readjust the timer to compensate for variations in day length. In summer and autumn, the on-time hours will be moved forward and the off-time hours will be moved back; in winter and spring, the on-time hours will be moved back and the off-time hours will be moved forward.

Input for twilight sensor (not included in the supply) working according to ambient light.

Microprocessor-controlled, with status and settings indicated via an LCD display. LED status indicator, and USB input for copying parameters for backup or to other timers of the same model.

The time switch has a polycarbonate cover to prevent accidental manipulation.

The electrical contact it has is 1 NO/NC switch contact with high switching capacity.

The setting range is from minutes/hours, with time steps of 1 minute.
